JAMES B. MCCAUGHEY, OF PAWTUCKET, RHODE ISLAND.

DAMPER-REGULATOR.

To all whom it may comern: Y

Be it known that I, JAMEs B. MGOAUGHEY, a citizen. of the United States, residing at the city of Pawtucket, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Damper-Regulators, of which the following isa specification.

My invention relates to a device for autoregulating the dampers of steam and hot water boilers, and is a device essentially adapted for use in connection with boilers for heating dwellings.

The invention consists in combination with a time-clock having the usual auxiliary or alarm winding mechanism and hour-setting dial, of an adjustable bracket adapted to be secured to the ceiling and arranged to support the clock, a depending lever from.

ans 7 te i on of said brac et and arran ed to be li dld iii a temporal position by the windmg-stem of the auxiliary mechanism of the clock, and a latch-arm ada ted to be pivotally mounted on the usual bar having chain-connection with the ash pan damper and smoke pipe damper of a" oiler. I The object of my invention is to rovide a device adapted to be actuated by t e auxiliary winding mechanism of a time-clock, to automatically act at a certain fixed time, to release the Weighted cross-bar having connection with said dampers and permit the latter to operate in retaining the heat of the boiler within the apartments of a dwelling.

My invention consists of the novel construetion, arrangement and combination of parts, as hereinafter described and specifically set forth in the claims.

In the accompanying shee.f; of drawings,

Figure 1 re resents a perspective view of my improved evice, as in operative position to regulate thedampers of a boiler. 7 Fig. 2 is a front elevation of my device, showing a timeclock m-ounted thereon. Fig. 3 is a side elevatioirof the device, showing its releasing members in their normal or set position, an

also indicating said members in. dotted position, as when the device acts to operate the ampers, and, Fig. 4 is a rear elevation ofthe device, showing the windin stem of the auxiliary mechanism of thee ock, as engagmg to temporarily hold the releasing membars in their normal osition.

Referring to the drawings, a designates a bracket which supports a time-clock,'whose mechanism actuates my improved devicef ortion entering the tube b, in the manner s own in Figs. 2 and 3. A setscrew 71 is employed at the lower end of the tube 6, to impinge ingthe band fin a A circular clock i, of the ordinary alarm type, is mounted within the band f, which embraces the circular case i of said clock, and said band is divided at its lower portion so as to dispose downward flanges f fwhich against the shaft 9 in holdfixed position.

. are perforated to receive therethrough a bolt aracters indicate like y for clamping said band firmly upon the case of the clock. This clock is provided with the usual secondary or alarm mechanism (not shown) and its time-setting dial A depending trip-lever 7c has its upper end pivoted to the extension f of the circular band f and the lower end of said lever is yoke-shaped, as at it, to engage the end of a latch-arm Z. This lever 7c has an integral flange k arranged about midway its length to permit the cross-pin m, of the clock auxiliary mechanism, to engage thereupon and to hold said lever 7c in towards the rear face of the clock, in the manner shown in full lines ip The lower end of the latch-arm Zis pivotally mounted on a stud n which is secured in the side of an inverted U-shaped piece 12,, and said stud is screw-threaded to receive a nut n to impinge against in holding said arm in a fixed vertical position upon the member a. The upperend of the latch-arm Z is cut away, on-its side nearest tl-e clock, so as to leave a narrow beveled shoulder to rest against the bottom lever Zr. The U-shaped piece or saddle n is adapted to be mountedupon the common cross-bar 0 having chain connection with.

the boiler-dampers, and said saddle is provided with a set-screw n to impinge against in holding the former in proper position upon said bar. I

The lever 7c and arm.

Z form the releasing members of my device.

The cross-bar 0 is a circular band f an inclined position Figs. 3 and 4.

edge-of the yoke k of the hub f of said band the boiler, as shown in Fig. 1.

- oelock the following morning, the operator rod m of said winding-stem) in the manner a anisin of the clock, by means of its windingv pivotally mounted on an u ri ht 29,.wh1ch Z extends from the top of the oiler g, a'nd the saddlepiece n, of the releasing member 1, is secured at one side of the pivot center of said bar and at a point towards the front of the boiler, while the usual fixed weight r is secured at the other side of the pivot center of said bar and at a point towards the rear of A chain s connects from ohe end of the bar oto the ashpan damper t, and a second chain a connects from the other end of said bar to a levers which is arranged to swing open the damper o of the smoke-pipe w, as in the ordinary arrangement of parts shown in Fig. 1.

Having now described the parts embodying my improvement, the operation of the device is as follows: Assuming the timemovement of the clock to be in operation and registering the time of hour as after ten at night, and it is desired to have the device regulate the boiler-dampers at- -say five first winds up the auxiliary or alarm mech stem as, after which the lever is is swung 111 Ward; y to its normal angular position to permlt its liange k to catchand rest upon the crossshoen in Figs. 3 and 4, next, the stem :1: is turned in order to cause the hand to point toward the hour of 5 on the hoursetting dial i and "finally the latch-arm lis swung over to en- V the yokc-end 7c of the lever is, thereby 1 down the bar 0 and causing the dam per t of the ash- )an to close' and at the same time cause the damper of the smoke-pipe w to open, as indicated by dotted position a in Fig. 1. As soon as the clock registers the hour of 5 its time-movement will actuate the auxiliary windingmechanism of the clock and thereby cause rotation of the windingstein m, thus releasing its cross-rod m from ement with trip-lever 7c and as the eh m revolves, its end ortions strike the upper part of the flhnge which ,s parallel with the lever is, and forces i lever from its normal angular osition point closer to the clock, thus t 1e yoke he lever A is made free of contact with he beveled shoulder of the latch-arm Z and ht r carries said arm to the dotted ,,msho'w'n in Fig' 3, when the aslwpan e1 will then have lifted to its opened position, as at t in Fig. 1, and-at the same time the damper/ of the smoke-pipe wwill have closed by gravity, to the dotted position indicated at 13 in said figure. Thus the heat of the boiler is retained to generate steam or hot water in the service pipes of the dwelling j i By having the bracket a designed in sub 1, stantially two parts, one stationary part, as and the movable part, as g, telescoping the former, accommodates the device I to be readily adjusted to suit the height of dis tance between the cross-bar 0 of the boiler and the ceiling of its room.

By the sim le arrangement of releasing members ic an( Z, these parts permit of being readily adjusted to be operated upon by the rotative action of the winding-stem m By my construction and arrangement of parts, I provide an automatic device that contains initself all that is necessary to assure a proper working of the dampers of steam and hot water boilers, and at the same time a device that is simple, durable and ineX ensive to manufacture;

Nhat I claim and desire to secure by Lette rs-Patent, is-

1. In a dam er-reg'ulator for a boiler, the

combination with a time-clock having an auxiliary mechanism, a stem for winding said mechanism, and an hour-setting dial, respectively, of a bracket adapted to be see cured to a ceiling and having a support'for said clock, said bracket having means to permit adjusting said clock in a fixed position, and also having an integral extension from its clock support; a depending trip-lever pivoted on the extension of said bracket and arranged to be held in an inclined temporal position by the stem of the winding mechanism, and said lever having an integral yoke formed at its lower end; a cross-bar having connection with the dampers of a boiler; a saddle-piece adapted to be secured on said bar; and a latch-arm having one end pivoted on said saddle-piece and its frcc'end to engage in the yoke of said lever.
